🎯 Who Actually Pays for This
Start local, start small:
Don't pitch to chains or franchises. Find the independent restaurant owner who's personally answering WhatsApp messages at 11pm. They feel the pain. They'll pay to make it stop. Get 3 clients like this before scaling.

✨ Customizing for Each Client
The magic is in the system prompt. This is where you turn a generic AI into "Maria from Joe's Pizzeria" who knows the menu, hours, and how to take reservations.

How to pitch the price:
"Your receptionist costs $15/hour and works 40 hours. That's $2,400/month for someone who can only handle one conversation at a time, needs breaks, and goes home at 5pm.
My AI assistant costs $300/month, handles unlimited conversations simultaneously, works 24/7, never calls in sick, and answers in 2 seconds. Even if it just handles 20% of your messages, you're saving money."
